Calcium and Hectorol drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Calcium (calcium) and Hectorol (doxercalciferol). Common drug interactions include nephrogenic systemic fibrosis among females and chronic kidney disease among males.

The phase IV clinical study analyzes what interactions people have when they take Calcium and Hectorol. It is created by eHealthMe based on reports of 23 people who take the same drugs from the FDA, and is updated regularly.

female:

Nephrogenic systemic fibrosis (involves fibrosis of skin, joints, eyes due to kidney disease)

Death
Dehydration (dryness resulting from the removal of water)

male:

Chronic kidney disease
